KlNK-PREVENTER FOR SILK-SPINNING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 487,334, dated December6, 1892.

Application filed March 2, 1892.. Serial No. 423,540. (No model.)

To aZZ whom it may concern:

Be it known that we, EDWIN OLDFIELD and PETER FLYNN, both citizens ofthe United States, and residents of Norwich,in the county of New Londonand State of Connecticut, have made certain new and useful Improvementsin Kink-Preventers for Silk-Spinning Machinery, which improvements arefully set forth and described in the following specification, referencebeing had to the accompanying two sheets of drawings.

This invention relates to machinery for spinning or for doubling andtwisting silk, and has for its object to prevent the kinking of the finestrands of silk when the machine is stopped; and said invention consistsin a simple device formed as a wire loop which may be brought intoservice at the proper time to hold the strand of silk taut.

Our invention further consists in mechanisms connecting said wire loopswith the belt shipping mechanism in such manner that the starting orstopping of the frame will serve automatically to bring into use orwithdraw the entire series of kink-preventers throughout the frame.

It is a commonly-known fact that when a silk-spinning frame isstopped-as, for example, at the close of the days work or at thenoon-hoursuch strands of silk as become slackened immediately doubleupon themselves and become badly kinked.- Owing to these strands beingvery fine and easily broken, the operation of straightening out suchkinks becomes both a tiresome and ex-' pensive one. Frequently thestrands are broken and have to be knotted, in which case the quality andvalue of the spun silk are materially lessened.

The drawings hereto annexed illustrate our invention, Figure 1 being across-sectional view of portions of a spinning-machine frame, showing inproper relation to each other the delivery-spool, the take-up bobbin,and such other portions of the machine as are immediately connected withour invention. Fig. 2 is an enlarged perspective view of the beltshipperrod, also one of our kink-preventing devices, and of the parts by meansof which action of the kink-preventers is efli'ected when theshipper-rod is moved in either direction, as hereinafter explained indetail. Fig. 3

shows the driving-pulleys of the machine with portions of the beltscoacting therewith, and also explains the manner of connecting theshipper-rod with the principal of said belts. In Fig. 4 I have shown theshaft which carries the series of kink-preventers, and also asupplemental shaft or rod upon which said preventers rest when inservice. Fig. 5 is a front view, in elevation, of several of thedelivery spools with their spindles and the belt by means of which theseries of spindles is rotated. This View also shows the kink-pie ventersin their elevated position-that is to say, the position which theyoccupy during the operation of spinning.

In the drawings, the letter a denotes the delivery-bobbinsuitablymounted upon spindles b, here shown as provided with a pulley b,which is engaged and rotated at proper times by a belt a, which engagesthe rear side of the entire series of spindle-pulleys throughout thelength' of the machine, as perhaps best explained by Fig. 5. Thespindles bare journaled in the usual manner in the lower machine-rail b.

c denotes the usual take-up roll at the top of the machine; 6', aguide-eye, and f the strand of silk, the parts thus far described beingthe same as in silk-spinnin g machines of ordinary construction.

Referring to Fig. 3, g denotes a vertical shaft bearing a loose pulley gand fast pulley g of equal diameters, which are engaged and controlledby a main drivingbelt h, and also a third pulley 9 fast on the shaft g,which last-named pulley carries the belt 0, already referred to inconnection with the spindlepulleys.

h denotes an angle lever fulcrumed at 71 1. and having a loop or eye atthe end of one of its arms through which the belt h passes, the free endof the other arm of said lever being In the rear of the series ofbobbinsa (about i machine, upon which is loosely mounted a series ofangle-armslc, corresponding in num;

her with the spindles of the frame, each an glearm having secured to itshorizontal portion a wire is, which extends outward and terminates in aring-shaped coil thatis concentric with the upper. end of the. bobbinand atleast. a complete circle of which is in the same plane and touchesthe bobbin with which it coacts at all points when the wire is droppedupon said bobbin. The several angle-arms may be prevented from lateraldisplacement upon the shaft 1'' either by suitable collars secured tosaid shaft on either.v side. of;- the angle-arms or by pins driven intosaid shaft, as shown in Fig. 2. Between .-s haft and the. line 1 ofbobbins is a supplemental; shaft m- 0a which. is'suppprtedby the.freeends of armsgm', secured; .to the .shaft in such man-ner that when saidshaft ;is gpa xgtly rotated tthevarmsm and rod m are liftedco p din 1em-ti e se .o kn set venters lo rest by gravity on the. rod and it willbe; understood thatwhensaidarod is raised the. kink-preventers arecarried: upward at the. sametime...

(See Fig.5.)
